Above fifteen doors and windows in the Louis XV-style Grand Ballroom are lunette paintings created specifically for Whitehall. These paintings, painted on canvas and attached to a solid support, alternate between Watteau-style bucolic or pastoral scenes and Boucher-style scenes with Cupids. The Grand Ballroom chandeliers, like all chandeliers original to Whitehall, were made by Edward F. Caldwell & Co. and are hung with Baccarat crystals. Twelve original gilt bronze and crystal sconces surround the room and contain typical fruit shaped crystal drops.
In 1903, the Grand Ballroom was the scene of the Bal Poudré, a lavish party given in honor of George Washington's birthday. The Florida Times-Union called the Bal Poudré "the most brilliant social function in fair Florida's history," while the New York Herald described the event as "one of the most sumptuous social affairs ever attempted south of Washington." At the Bal Poudré, guests danced the Minuet and the Virginia Reel.
